Howdy! Are you using something like Ollama? You should be able to select 'OpenAI compatible' as an option for 'stacks configure' and point an OpenAI-like endpoint to it. In Ollama's case, this should be http://localhost:11434/v1/
More information on this can be found here:

Let me know if you have any questions!
